AN'ITSKIDDING ARMOR FOB TIRES.

Specification of Letters Patent.

Patented Nov. Reid Application filed February 24., 1913. Serial No. 750,331.

To all whom it may concern:

Be it known that we, HENRY W. WHITE and AURIN T. SHELDON, citizens of the United States, residing at Atchee, in the county of Garfield and State of Colorado, have invented certainnew and useful Improvements in Antiskidding Armors for Tires, of which the 'follggving is a specification. l 5

This invention relates to anti-skidding armors for tires; and it has for its object the provision of an armor which when applied to the tire will prevent excessive wear on the same and insure a proper purchase of the machine against the ground to positively prevent the skidding of the machine.

Another object of the invention is the provision of metallic tread sections or straps. which may be arranged cqui-distally around the tire and provided with oppositely inclined calk forming flanges which will be projected for such distances beyond the surface of the tire as will permit said edges to be properly advanced into the surface of the ground as the wheel revolves.

A further object of the invention is the provision of metallic tread sections or straps which may be connected with the wheel in such manner that will permit them to yield radially on radial deflection of the tire.

'K still further object. of the invention is the provision of means for connecting the tire embracing straps in series around the tire and the relative arrangement of the straps so that any particular section of the device may be removed with facility when worn.

Another object of the invention is the provision of means whereby the device may be quickly connected with or disconnected from any standard form of wheel and tire.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawing :Fig ure is a side view of a vehicle wheel, showing the thereto; Fig. 2

is a top plan view of a portion of the device removed from the wheel; Fig. 3 is a view similar to Fig. 1, showing a slightly modified form of the invention; view of one of the tread sections; Fig. 5 is a section on line 55 of Fig. 4.

The device comprises yieldable metallic Fig. 4 is an edge.

tread sections 1, which are preferably an ranged equi-distally around the tire A of:

the wheel B conventionally illustrated here- 1n. These sections are formed from fiat metal strips which are curved so as to eni-- brace the tire, and as illustrated in 5 each section has its main body portion curved transversely, as at 3, whereby to con-- form with the curvature of the tire A to readily adapt itself thereto. The side edges of the section are stamped, so as to present oppositely extending calks 4c tapering to ward the extremities of said section, which are arranged substantially at an obtuse angle to the plane of the main body of the section so that relatively sharp edges 5 of the calks will be operatively exposed and arranged for presentation to the surface of the ground, as the wheel is revolved,'thereby maximizing the purchasing cfiiciency of the wheel with the ground to prevent skidding of the wheel.

The calks 4t terminate slightly within the ends of the tread'sections, and as illustrated the ends of the sections are provided with knuckles 6, which are alined with knuckles '7 of hinge plates 8, which are disposed are provided with knuckles 10 normally lying in vertical alinement with the knuckles 6 and are alined with knuckles 11 of hinge plates 12. These alined knuckles are connected together by hinge pins 13, as shown in Fig. 4E. From this construction it'is evident that each tread section is rendered radially flexible and laterally flexible, so as to respond to all yielding movements of the tire.

The attaching device for holding the tread sections properly associated with the tire includes spaced series of arcuate rod sections 13, which are preferably located at the sides of the wheel at points adjacent to the rim. The sections are arranged relatively, so that the rods of one series are oifset from the rods of the other series, as shown in Fig. 2. In other words, the rods of one series are located immediately opposite the spaces between rods of the opposite series. The hinge plates 12 are provided with loops l l, and'as illustrated the loops of each tread section 1 receiveone rod of each series of rods forming the attaching or connecting 'device. The terminals of the rods are extended struck at against the loop, as shown in Fig. 2. The ends 15 are bendable, so as to permit any one or a required number of tread sections 1 of the armor to be removed from the tire without affecting the other sec- The attaching or in the tionspf the device.

connecting device shown 3 comprises ring sections 16, 17- and latter having terminal eyes 19 fitted eyes 20 of the sections 16 and 17, as shown. The sections 16 and 17 are provided with right angularly extending eyes 21, through which a fastening bolt 22 is extended and arranged, so that the sections 16, 17 and 18 can. be adjusted to securely clamp the tread sections 1 of the armor against the tire. The tread sections 1 shown in this form of the invention have their inner plates 12 provided with companion knuckles 23, which are spaced relatively and disposed beside lugs 24, which extend from the rod sectionsoi' the connecting member. These lugs serve to hold the tread sections against creeping,'as will be understood.

From the foregoing description, taken in connection With the accompanying drawin Fig. 18, the

' ings, the construction and operation of the invention Will be readily understood With-. out requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to Without departing from the principle or sacrificing any of the advanta es of this invention, as claimed.

'aving thus described our invention, .what

vide calks that taperstowa'rd the extremitiesof the section, a pair of oppositely disposed plates having their upper extremities hinged to the extremities of said section and a second pair of plates having their upper edges hinged to the lower extremities of the first mentioned plates in vertical alinement with their hinged connections with said tread section, said second mentioned plates having their lower extremities formed into loops that are disposed with said first mentioned passing through the loops.

In testimony whereof We afhx our signatures in presence of-two Witnesses.
